IMPROVEMENT IN'WAGN-LAMP SUPPORTS.

Specification forming part of Letters Patent N o. 167,736, datedSeptember 14, 1875; application filed July 19, 1875.

To all whom it may concern:

Be it known that we, THOMAS BOUDREN and GEORGE H. J 0HNsONof Bridgeport,in the county of Fairfield and in the State of Connecticut, haveinvented certain new and useful Improvements in Supports for Lamps forfire apparatus and other vehicles; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon making a part of this specification.

Our invention relates to a new method of attaching lamps to lireapparatus and other vehicles, the object being to protect the lamp andkeep it from being extinguished by the Violence of jolting. l To thisend the nature of our invention consists, principally, in sustaining thelamp between two springs, so arranged that they act in oppositedirections on each other, each receiving the vrecoil of the other inturn. It further consists in `so arranging the shape of the interior ofthe barrel or tube of the holder, in which the springs are placed, witha correspondingly-shaped diaphragm, that the lamp will be free to movevertically, but has no lateral or revolving motion. Our inventionfurther consists in combining a setscrew with the socket in which thelamp is placed, so that the lamp may be held in different positions, allas hereinafter more fully set forth.

In the annexed drawing, Figure 1 is a vertical section of our invention,showing the lamp hung to one socket. Fig. 2 is afront elevation. showingthe lamp hung between the sockets.

A represents a vertical barrel, tube, or case, having its interior madehexagonal or polygonal in shape. In this tube or case is placed adiaphragm, B, ofcorrespondin g size and shape, on each side ofwhich-that is, above and helow-is placed a spiral spring, c. c is thespindle, which sustains the lamp, and which is provided with a shoulder,D, to abut against the socket in which the spindle rests. On the bottomof the case A is screwed a followernut, E, through the center of whichthe spindle C passes, and which prevents the springs from dropping out.vThe spindle C fits in a suitable socket at some convenient point on thevehicle, and is held by means of a set-screw, F, so that it may beturned in any direction desired and held permanently in such position.The case A is provided with an arm or flange, G, to which the lamp H isattached by any suitable means. The upper end of .the spindle C isusually attached to the diaphragm B by screw-threads, as shown, so thatthe diaphragm can be readily removed in order to place the lower springin position. The springs a may be made of wire in spiral form, as shown,or of rubber or other suitable material.

By this invention the weight of the lamp is in immediate contact withthe springs, and hence it is obvious that the violence resulting fromhaving no spring and the jumping tendency of only one spring are fullycorrected, and the practical result is that, the lamp will burn freely,while otherwise it would be eX- tinguished.

It is not essential to attach the lamp to the case A at the same point.It may be secured on top of the support. Neither is it essential to haveboth the springs in one case, as for certain jobs it is more desirableto have two spindles and cases, the springs being so arranged in eachcase with reference to the diaphragms on the supporting-spindles thatthey act in opposite directions to each other, and the lamp is suspendedbetween the two.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

l. In combination with a lamp for vehicles, one or more supportsprovided with springs arranged with relation to the weight of the lamp,'so that they will act in opposite directions, substantially as hereinset forth.

2. The combination of the lamp-supporting case A, interior diaphragm B,springs a a, and spindle (l, all constructed substantially as and forthe purposes herein set forth.

3. In a lamp-support, the combination of the case A, springs c a,diaphragm B, spindle G, with collar D and the set-screw F, allsubstantially as and for the purposes herein set forth. v

In testimony that we claim the foregoing we have hereunto set our handsthis 23d day of June, 1875. l
